The code is a substantially modified version of a SparkFun repository, which they provide on the order page for the tilt sensor. I had to reverse engineer the wiring for the sensor from the frustratingly short video on that order page. After I had it operational, the next challenge was to integrate some variables for debugging, and add a publish function so that the alerts would be logged and viewable remotely. This was accomplished using experience from our class tutorials. The final step was to wire up a kill switch, so that the alerts could be disabled while at home. After some digging in the lab, I found one latching button. About a dozen configurations later, Steffen helped me solve the floating voltage issues and I had a solid on/off signal. A few more lines of code to define the status of the switch (and add it to the IF statements) and the device was fully operational.
Is this a good/useful/informative piece of content to include in the project? Have your say!
